Courtesy titles Princess Reuss and Countess of Plauen are also in use because of her third marriage. Lyngstad did not find international fame, however, until she joined ABBA, who have sold over million albums and singles worldwide, making the group, which included her second husband Benny Andersson , one of the best-selling music acts in history. After the break-up of ABBA, she continued an international solo singing career with mixed success, releasing the albums Something's Going On and Shine ; the latter being her last international album.
In , Lyngstad recorded her final album in Swedish, Djupa andetag Deep Breaths , released by Anderson Records , before retiring from music. Her grandmother took any available job while living there, whereas Synni remained in Norway and worked for a time in the south of the country. Synni died of kidney failure soon afterward, aged 21 years, leaving Anni-Frid to be raised solely by her grandmother.
Anni-Frid would grow up believing her father had died during World War II as his ship had been reported to have sunk on its return to Germany. During her childhood, Anni-Frid had close contact with her family, particularly her uncle and four aunts, at her birthplace during the summer holidays.
She was close to her aunt, Olive, who once stated that she saw how lonely and subdued Anni-Frid was, and who consequently always did her best to make her feel loved and welcomed during her visits.
In , the German teen magazine Bravo published a poster and a complete biography with details of Anni-Frid's background, including the names of her mother and father.
